Appendix B
Reverting the Card to Factory
Image
The Alveo
™
card can be reverted to the factory image, also known as golden. This requires that
XRT 2019.2 release or later is installed on the same system as the Alveo accelerator card. The
steps to revert the card using this method are listed below.
1. Open a terminal window.
2. Run the following command, where
card_bdf
is the BDF of the card to revert to golden.
$ sudo /opt/xilinx/xrt/bin/xbmgmt flash --factory_reset --card
<card_bdf>
3. Enter y to continue. The following message is displayed on completion.
Shell is reset succesfully
Cold reboot machine to load new shell on card
4. Cold boot the system so the card FPGA uses the new image.
5. Confirm the card has been reverted to factory image by running the following command.
$ sudo /opt/xilinx/xrt/bin/xbmgmt flash --scan
An output similar to the following is displayed.
Card [0000:65:00.0]
Card type: uxx
Flash type: SPI
Flashable partition running on FPGA:
xilinx_uxx_GOLDEN_x,[SC=x.x]
Flashable partitions installed in system: (None)
In this output, under
Flashable partition running on FPGA
, note
GOLDEN
in the
name. This indicates that the card has successfully been reverted to factory image.
IMPORTANT! If the GOLDEN_2 image is running on the FPGA, carefully review the design advisory
for Alveo data center accelerator card golden corruption, found in the Xilinx Answer Record
. Complete the repair instructions associated with the Xilinx Answer prior to proceeding.
IMPORTANT! Si l'image GOLDEN_2 est en cours d'exécution sur le FPGA, consultez attentivement
l'avis de conception relatif à la corruption dorée de la carte accélératrice de centre de données Alveo,
disponible dans l'enregistrement de réponse Xilinx
. Suivez les instructions de réparation
associées à Xilinx Answer avant de poursuivre.
